As you can t run --disable-web-security and a normal chrome in parallel it s probably a good solution to use Opera for --disable-web-security  Here is how to create a launcher for opera on windows  By the way  Opera has the same debugging tools as chrome   http   www opera com      opera-browse-dangerously bat cd c  Program Files Opera  launcher exe --disable-web-security --user-data-dir  c  opera-dev    PS  Opera doesn t display any notification when started without web-security

Check if you have Chrome App Launcher  You can usually see it in your toolbar  It runs as a second instance of chrome  but unlike the browser  it auto-runs so is going to be running whenever you start your PC  Even though it isn t a browser view  it is a chrome instance which is enough to prevent your arguments from taking effect  Go to your task manager and you will probably have to kill 2 chrome processes
